Introduction to the cowhide drum: The treasure of the Anqian Palace is the Qing Dynasty cowhide drum, which is known as the king of drums in the world. The drum is a double-sided drum. The height of the drum is 1.5 meters. The drum surface is oval and the average diameter exceeds 1.5 meters, each end is covered with a complete piece of cowhide. Because the terrain is high and not susceptible to moisture, the drum is well preserved. Knock it with a drumstick, and the sound will be as loud as thunder, resounding through the sky, making people feel like heavenly soldiers and generals summoned outside the Nantian Gate, looking down at the people and the earth, and you will suddenly feel a sense of awe of the gods when you raise your head three feet.
